Well i think the idea of ww2 Soviet technological inferiority gets exaggerated a lot, there were some things they didn't do quite as well at compared to the western allies or Germans but the whole idea that the Red Army overwhelmed the Soviets by the sheer mass of millions of poorly armed, poorly trained conscripts gets often significantly exaggerated.

Prior to ww1 Russia was in a process of increased industrialisation, in terms of the proportion of its population that worked in industrialised manufacturing roles and the like compared to farmers, including quite a lot that were still fairly subsistence based. But the machine of industrialisation was beginning to pick up steam. This had been one of the factors that had made the Germans so nervous about the Russians and caused some within the German and Austro-Hungarian Armies to believe that it would be necessary to attempt to curb Russian power before this process continued, Russia for a long time had vast amounts of resources and man power at its disposal, but historically had often had trouble effectively mobilising that, being able to turn resources into weapons, men into soldiers put them both together and take them to where the fight was happening. But as the Russian rail network expanded and its process of industrialisation continued its ability to do these things was increasing significantly. As a result many in the German army and the like were concerned that if let unchecked into the 1920s the Imperial Russian Army would be a steam roller they couldn't stop.

In terms of Russian tech in world war one it was a fairly mixed bag. On the one hand they had a pretty impressive reserve of things like munitions stockpiles leading up to the conflict, some 12 million shells and over 7000 guns though like most powers these were largely field guns which turned out to be mostly obsolete compared to larger guns better designed for indirect fire. The problems really began to arise later on, the Russians armed forces had a decent arsonal by the standards of 1914, but as the war forced innovation, an increased focus on effective combined arms tactics between infantry and artillery. And Russian industry struggled to keep up with the demands of changing over into these new weapons compared to countries like Germany, France and Britain if not as bad when comparing them to other forces like say Austria-Hungary or Bulgaria. These other countries increasingly shifted from using a lot of field guns with shrapnel rounds which are effective against troops in the open and mostly used with direct fire and a few heavier guns to using mostly heavier howitzers and mortars with HE shells and indirect fire which was much better suited at dealing with entrenched targets in a modern environment and coordinated to both engage in artillery duels and support infantry. Russia attempted to but struggled to keep up. Only managing to produce a few hundred such guns and having to import some from Britain.

In terms of things like machine guns at the start of the war it had a detachment of 4 machine gun sections each with 2 machine guns in each on paper. Someone with more information than me maybe able to tell you the extent to which such numbers were matched on the ground, its pretty common for numbers on paper to not match those achieved on the ground. But if on the ground numbers is not too different from paper numbers this wouldn't be too bad compared to for example the Austro-Hungarian military, slightly less than some of their counter parts in maybe the British or German forces but not massively behind. These were the big PM M1910s which was basically a Maxim gun copy. In 1914 this was nothing unusual, very similar guns were used by many of the forces. But like the artillery things moved faster than Russian industry could keep up with. By the mid war everyone wanted more machine guns in their units and lighter ones. Lighter machine guns became necessary as a tool for suppressing enemy troops to attempt to take enemy positions and for then holding them against counter attacks once taken. The Russians were unable to produce any over their own. They did purchase some from other powers, some very good guns like the Madsen Machinegun, the weapon was used by both sides by neutral Denmark, it was a very good light machine gun and the Russians had even been using it from back in the Russo-Japanese war in some small numbers making them a little ahead of the curve in that regard. But purchasing more on the scale that might have been necessary to conduct the war wouldn't have been practical, other weapons like the Anglo-American Lewis machinegun and the French Chauchat were also used in this roll but while the Lewis gun was good but expensive and the Chauchat which had reliability issues again the numbers they were able to import just weren't there. They managed to produce more of the M1910s and although weight wasn't so much of an issue where other countries were moving to produce things like Vickers Machineguns which were able of similar performance while being lighter the Russians stuck with this older design.

They did have some problems though as the war went on meeting the demand for more rounds, more guns, more weapons of every kind really. For example the Russians found that they struggled to produce enough rifles to meet the required demand of the war. The M1891 Mosin–Nagant was the standard issues rifle for the war and while I would describe as broadly serviceable but unexceptional. The problem came however in that as the scale of the war ramped up the size of the army the Russian Empire would have to produce to fight it was clearly going to be larger than their industry could arm, and so Mosin–Nagants were produced overseas in places like the united states. This was forced to be supplemented by older weapons like the Berdan rifle which was a rather unwieldy in length an single shot weapon and civilian weapons purchased from overseas like the Winchester 1895 lever actions which had the downside of being clunkier to operate from the prone position and a little more awkward to cycle the action while keeping the sight picture of your target. There were also a few examples of some advanced rifle designs like the Fedorov Avtomat but these were not produced in numbers necessary to make an impact on the battlefield by the time the October revolution.

In terms of the kinds of things that came into play as the war went on the Russian Empire never manged to produce a particularly large or advanced airforce. Their aircraft were often either older ones adopted from people like the French and for they never managed to produce the more advanced forms of tech that was used in the late war like interrupter gear.

Likewise for tank tech you may have heard of the rather strange attempt at making the Tzar Tank, this obviously never worked particularly well. Beyond that Imperial Russia army had attempted to purchase French and British Tanks during the war years but civil war began before they could ever been deployed there and it wasn't until it was the White Army fighting the Reds among others that these tanks actually saw action in Russian.
